The number of items in an NFT collection will depend on the project or artistic proposal and the creators' objectives and ideas. There is no pre-established formula, and customs and practices can quickly vary in the Web3 world.
If a project aims to raise more capital through secondary sales, they may want to create a collection with a higher number of items, although there is no definitive recipe.
Until recently, it was more common to see collections of 10,000 NFTs. However, lately, many creators have been deciding to sell their collections in small batches.
Each creator will need to evaluate what will work best for their project. The Tokenizer by SPOZZ allows the creation of collections with different quantities (up to a maximum of 10,000 items) and launching them in batches. To learn more about the Tokenizer, visit here.
